Your computer might be set to “Obtain DNS server address automatically”. If it is, then change it to “Use the following DNS server address” by clicking the radio button.

If your computer is already set to “Use the following DNS server address”, then there will be some numbers (IP addresses) entered into the boxes below.

Write these down and keep them. If you decide later that Open DNS isn’t for you, you can return to the original settings by re-entering these numbers (IP addressees) into the relevant boxes.

"Obtain DNS server address automatically" is selected.
Change this setting to “Use the following DNS server address”
"Use the following DNS server addresses" is selected. Callout reads "Write these numbers down".

Once that’s done you can close any open windows and launch your web browser (Chrome, Edge etc). All your DNS queries are now being resolved by the Open DNS servers.

Test it out. Try making several searches and checking that you actually reach the websites. Start with a couple of well known sites such as Amazon, eBay etc. If that works OK, try a few random searches.

Open DNS Content Filtering.

One of the best reasons for using OpenDNS is its ability to block adult websites before they even load onto your computer. You simply can’t get to them.

You can search Google for them and you’ll see the results show up as usual, but if you click on a link, you’ll find that it’s blocked.

Known phishing websites are also blocked.

That website is blocked.

Content Filtering Isn’t Perfect.

Any sort of content filtering will always make mistakes. Sometimes websites that should be blocked will actually get through and other times perfectly legitimate sites will be blocked. Nothing’s perfect, it’s just a fact of life.


Setting up a computer like this, to use the OpenDNS servers, only affects that one machine. Any other devices that you’ve got in the house (other PCs, smart phones etc) will still be using your ISP’s default DNS servers.
